With a total of five patents to his name, Yang's work showcases his expertise and dedication to advancing technology.

Latest Patents

One of Yang's latest patents is a method for preparing a novolac phenolic resin/silica hybrid organic-inorganic nanocomposite. This method involves grafting a glycidyl alkylene trialkoxy silane to a novolac phenolic resin in an organic solvent to create a modified resin. The process continues with the mixing of a tetralkoxy silane, an acid, and water, leading to hydrolysis and condensation reactions that form a Si-O-Si bonding. A curing agent is then added, and the mixture is heated to produce the final nanocomposite. Another notable patent is for a process for preparing poly(urea-urethane). This involves reacting an amino-terminated polydimethyl siloxane with polyisocyanate to create a prepolymer, which is then reacted with a chain extender in the presence of a catalyst. The resulting poly(urea-urethane) contains a significant percentage of hard segments and exhibits excellent surface resistance, making it suitable for applications in anti-static electricity and electrostatic discharge shielding.
